| Along with the rapid development of the insurance industry, the significance of information technology becomes important increasingly, which makes management and network of the insurance company more imperative. Therefore, the development of the unified information platform will help company to achieve centralized management system, including financial, human resources management, purchasing management and so on.According the specific sales management system (SMS), the system is one of the main business systems in insurance company. How to develop such application system software with a performance of high-efficiency, stability, reliability and good platform-transferability is studied in this work based on the J2EE platform. Staring from the business model of SMS, the requirement for the whole system is described and a flow chart with UML for this requirement is demonstrated as well. The persistent real entity and their mutual relation are discovered by case analysis. Then, a database model for this SMS is designed by real entity-relation model and the 3rd norm. Based on this model, the system architecture of the SMS is analyzed and designed. The J2EE system architecture implemented with MVC design mode categorizes the whole system into eight independent function modules, which greatly helps the collaborative development in the team. Inside each module, several J2EE key technology and classical JAVA design mode are used to implement the loose function-coupling among different modules. In the design of the controller module we use ActionServlet in the Struts Framework to realize the logical transaction between page transformation and modules. In the design of presentation layer, we choose the technique of JSP. Finally, we pack all these components and deploy it in the Oracle 10g Application Server.Through operation and testing of the system, it is proven to be stable and normal which fully meets the requirements in performance and function for business department. |
